I have a rooster who has water belly. He is also wheezing, but still moving around just fine. I’ve read a little bit about it. Is this caused by an underlying illness, or is it something I’m feeding them? They get their chicken feed. I’ll also dump a couple scoops of mealworms for all of my chickens in the am. Throw some garden scraps in there and also a couple handfuls of scratch…. Can it be caused by this diet??
